DIAMOND-SETTING.

SPECIFICATION forming part of Letters Patent No. 517,265, dated March 27, 1894.

' Application filed June 13, 1893.

To aZZ whom it may concern.-

Be it known that I, FRANK P. DAROY, a citizen of the United States, residing at the city of Kalamazoo, in the countyof Kalamazoo and State of Michigan, have invented a certain new and useful Diamond-Setting, of which the following is a specification.

My invention relates to improvements in diamond settings or mountings.

The objects of my invention are to provide a setting that shall give any desired tint or tints to a diamond and to lessen the amount of gold or other metal required in the construction of such articles, and to provide a setting that will more securely grasp the gem. I accomplish these objects by the device shown in the accompanying drawings, in which- Figure 1, shows an enlarged perspective view of my invention as applied to a shirt stud. Fig. 2, is an enlarged detail of one of the prongs B, and Fig. 3, is a sectional View on line 3-3 of Fig. 2.

Similar letters of reference refer to similar parts throughout the several views.

The setting here shown is adapted to a shirt stud. It consists of a base A having prongs B for holding the gem and a coil 0 for attaching the whole to a shirt front or to a scarf. The prongs B are hollowed out on the inside where they clasp the stone. The hollows are filled with enamel B either white or colored. The color of the enamel is not material to my invention, any color can be used to suit the taste of the maker or wearer, and the colors in each prong may differ and the colors in a single prong may be varied. In the setting here shown the prongs are hollowed out down to the base A, and this setting is intended for a diamond that shall entirely fill the prongs and reach down to the base A as it is not desirable to have the bare enamel appear below the stone. If the diamond comes only part way down the prongs B, the prongs should be hollowed out to that distance only. The sides of the prong should be pressed firmly against the stone in mounting so that the enamel will be entirely concealed. It is not necessary to hollow out the prongs so deeply as I have indicated, a slight depression sufficient to hold enamel is all that is required. Other color- Serial No. 477,448. (No model.)

ing matter than enamel might be used. I prefer enamel and have not indicated the coloring matter.

My invention is adapted to use wherever a diamond setting is to be used as for ear-rings, finger rings, pins, bracelets, studs, &c.

The use of my invention is not confined to the particular style of setting shown in the drawings. It can be successfully used in any kind of a mounting where prongs are used to clasp around the gem. It is however particularly adapted to those mountings that are comparatively open.

I am aware that glass and quartz ornaments have been mounted in sockets with coloring matter back of them, but such devices do not permit a free passage of light and do not as a consequence give the diamond itself the desired tint or tints, the substance itself being plainly visible while in my device it is impossible to detect the presence of the enamel or coloring matter without removing the diamond. By grooving the prongs they will when pressed against a diamond or other gem remain in closer contact and so hold it more socurely.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a diamond setting the combination of the base A, bearing the prongs B, and the enamel B in grooves on the inside of the prongs adapted to be pressed against a diamond mounted therein substantially as described for the purpose specified.

2. In a diamond setting having prongs the combination of the prongs with enamel placed in grooves on the side of the prongs next the gem and adapted to be pressed firmly against the gem for the purpose specified.

3. In a diamond setting having prongs the inner side of the prongs adapted to receive side with colored enamel in the groove for be pressed against the jewel for the purpose the purpose specified. specified. I
